Its a pretty obvious sample no offense since they released so music hype around the daft punk kanye collabo. But yeah to answer your question it samples the vokals from "harder better faster stronger" from daft punks discovery album at the time inovaiting the france house scene. It was later turned into an anime film called "Interstella 555", the look of the anime had a 70's feel and tracks from discovery served as the plot so in a nutshell like one big music video. Daft Punk is said to have a cameo in Kanye's video for stronger.
